Objectives
The fundamental objective of this course is to develop competences on modeling, analysys and design of automatic control systems for physical/chemical/biological processes. As a complement, it is exepected that the students will gain basic knowledge on instrumentation associated to automatic control - sensors, controllers, and final control elements - and on concpets of industrial automation.
Learning outcomes and competences
A student, after successfully concluding this course, should be able to:
- Design and tune classic controllers according to given performance criteria.
- Design and tune some advanced control strategies, performing a critical analysis of their pertinence.
- Identify the main instrumentation used in process control of physical/chemical/biological processes.
- Recognize the different types of idustrial communications and levels of industrial automation.
Working method
Presencial
Program
The main topics in this course are:
- Review of transfer function concept.
- Closed loop control (feedback).
- Dynamic behavior of closed loop control. Stability analysis.
- Controler tuning; criteria and methods.
- Controller design based on internal model control.
- Feedforward control based on dynamic and steady state models.
- Ratio control.
- Advanced control startegies: cascade control, time delay compensation control and split-range control.
- Representation of control systems using P&I diagrams.
- Industrial instrumentations for process control: sensores and transmiters, controllers, final control elements.
- Industrial automation.

Teaching methods and learning activities
Teaching will be based on presential classes for presentation and discussion of concepts and study cases. Software tools will be used for computer-based learning. Pratical exercises will take place using real PID control systems.

Eligibility for exams
Do the works or tests along the semester and be present at one of the final exams.
Calculation formula of final grade
The final classification, CF, is given by:
CF = 0.25 x AD + 0.75 x EX
where AD is the average score of the evaluation tests along the semester and EX is the exam score.
Special assessment (TE, DA, ...)
Final exam.
Classification improvement
Each student may choose between doing the second exam ("recurso") in order to improve only the grade of the first exam, keeping the grade for the distributed evaluation, ou improve all grades, so that the final grade will be that of the second exam.
